David Cottingham and Terry Hoyle! Both a bit more vintage now than when the picture was taken at the UK FOC Concours at Cottesbrooke Hall in June 2002.
I would not like to comment on whether either of these gentlemen has had any restoration work done. I suspect that they are both matching numbered examples though.
